Abstract
Cycle loading was applied to 40 Sprague-Dawley rat jejunums to increase their diameters using a balloon catheter filled with saline over a 30-min period, with each load lasting 3 min at 1-min intervals. The dilations were performed using 0.2 ml saline in group I, 0.4 ml saline in group II, 0.6 ml saline in group III, and no dilation in the control group. The percentage increments of increase in external jejunal diameter were 10.52 in group I, 48.38 in group II, and 68.08 in group III. Histologic changes were reversible in groups I and II and irreversible in group III. It is suggested that cycle-loading tissue expansion could be used as an alternative method for the treatment of intestinal atresias to correct discrepancies in the caliber of gastrointestinal lunens.
